Patented Apr. 22, 1930 SKI FASTENING Application filed Gotober 15, 1928, Serial No. 312,641, and in Norway October 19, 1927.

which Figure 1 is aside View of a part of a ski with the device.

Figure 2 is a plan view of the two parts of the device.

Figure 3 is a plan view of a toe-iron before the ears have been bent up.

Figure e is a cross section taken as indicated at line A-A of Figure 3.

Fig. 5 is a top plan view of a part of a ski with the device applied thereto,

Fig. 6 is a longitudinal sectional view through the coacting locking members,

Fig. 7 is a transverse sectional view through one of the members, and

Fig. 8 is a transverse sectional view through the other of the members.

The back-strap 1 is at each end provided with a metallic member 2, which is pivotally mounted on upright ears 3 and 4- on iron-bands 5 and -6 respectively,

either by riveting as shown in the drawing.

The iron-band 5- has dovetailed cross section (Fig. 7), and the iron-band -6 has a corresponding form (Fig. 8), so that it is slideable in the iron-band 5.

Inside the iron-band 6 a plate-spring -7 is riveted,

which is adapted toengage with a proper.

Then the iron-band 96- is inserted in the iron-band i5 from the opposite side, 7

I and it is then obvious that-the tip of the spring 7 will come in engagement with the teeth .8, so that theiron-bands can not be drawn from each other without special means. If for any reason it is wanted to loosen the back-fastening from the ski, a suitable device, for instance a thin metal strip S, (Fig. 6), is inserted'between the iron-bands '56, so that the engagement between the spring 7 and the tooth 8 is released and the other slots are overlapped, whereupon the iron-bands can be drawn'from each other.

lhe toe-iron 9, shown in the drawing, has along the edge lying behind the iron bands 5()' a that a steady rest for the iron band 5- is obtained, simultaneously as a through-slot 11 under the toe-iron is formed for p1ac ing a cross-strap 12, which isfastened to the buckles 13 of the back-strap 1, (Fig. 3).

The embodiment shown in the drawing is only given as an example, as alterations may be made without departing from the scope of the invention.

For instance the guiding depart 10 bent downwards, so

vices for the iron bands may be different from those shown in the drawing, and the automatic locking by the displacement of the ironbands in each other may be different from that shown, Without departing from the scope of the invention.

What I claim is:

1. A ski-fastener of the character de scribed, including in combination with a ski having a transverse slot therein and abackfastening strap, of interchangeable and lockable members slidably and removably mounted in said slot and each having one of the ends of the back-fastening strap secured thereto.

2. A ski-fastening device in accordance with claim 1, wherein both of the members are in the form of iron bands of dove-tailed shape in cross section and are slidably telescoped one within the other, one of said members being provided with a series of teeth, and a plate spring on the other of said mem .bers for engagement with the teeth of the first member so that the members cannot be accidentally drawn from each other.

A. sknfastenmg device in accordance with claim 1, wherein the outer ends of the members are each provided with an upright ear to which the adjacent ends of the backstrap are pivotally connected.

4:. A ski-fastening device according to claim 1 and in combination therewith, a toeiron arranged through the slot with the terminals extending above vthe upper surface of the ski, a downwardly bent portion adjacent the bottom surface of the slot to hold the upper surface of the medial portion of the toeplate against the opposite surface of the slot in the ski, said bent part coacting with the adjacent end of the slot to leave a passage adapted to accommodate a cross strap, and the medial portion of the toe-plate being also providedwith a through s1otfor receiving the interengag'eable and lockable members, substantially as and for the purposes set forth. v

In testimony whereof I have signed my name to this specification.
